Crossing the River

A farmer is trying to get the three items in the left river bank across the river to the right river bank.

The boat's maximum capacity is 100kg. The farmer is 70kg, the cabbage 4kg (it's a giant cabbage), the goat 23kg and the wolf 27kg

There are a couple problems however with these cargos when left alone. The wolf will eat the goat if left by themselves (the farmer crossing to the other side), while the goat will eat the cabbage if left by themselves.

Can you help Mr.Unknown Farmer?
